| description | Alteration in Land use land cover over time have demonstrated their significant role in shaping the patterns of UHI observed across cities worldwide. This research endeavours to examine alterations in LULC, and Land surface temperature (LST) in the Patna Municipal Corporation (PMC), Bihar. The application of remote sensing techniques and GIS methodologies was employed to scrutinize the satellite data encompassing 2002 to 2023. Additionally, ground validation was also executed to authenticate the observed modifications in LULC and temperature changes during the designated time period. Moreover, the correlations between LULC indices such as the NDBINDVI MNDWI), andNDBaI) With the Normalised LST (NLST) have been established. The results highlight an increase of 2990.31 ha in the area affected by UHI in zone 5 of PMC. The findings reveal a positive correlation between NLST and all indicators except NDVI and MNDWI. These two indicators exhibit a negative correlation, having coefficients of correlation value −0.606, −0.516, and −0.268, −0.245, respectively, during the specified time periods. The research contributes to a more comprehensive understanding of the spatial dynamics of the heat island effects in a developing country’s, and can be proved useful for mitigating its affect to ensure sustainability. |
